24 Claims.

This invention relates to printing machines of the kind wherein bill sections such as utility bills, insurance notices and the like are printed.

In machines of this kind the bill sections to be printed are sometimes severed from a web and impressions are usually made on both faces thereof from permanent printing forms in the machine.

Impressions are also made on the bill sections from the changeable printing devices which are sequentially passed through printing position in the machine. These changeable printing devices are filed in a predetermined sequence and are stored in drawers when not in use. When the machine is to be operated a plurality of these printing devices are introduced into a magazine in the machine from which magazine they are withdrawn and passed into printing position. Sometimes all of the printing devices passed through printing position are not to be used in a printing operation. However, in normal operation of the machine the successive passage of the bill sections and the sequential passage of the printing devices are in timed relation which must be maintained to insure proper operation and therefore if a printing device is not used in a printing operation upon movement into printing position the printing device feed mechanism must be operated in a normal manner while the operation of the other mechanism is interrupted.

The salient object of my invention is to interrupt the bill section feed when a printing device is not to be printed, and an ancillary object is to also interrupt the operation of other mechanisms in the machine operating on the bill sections whereby the aforesaid timed relation may be maintained.

The bill sections are severed from a continuous web withdrawn from a supply roll and another object is to move the web in a definite amount on each operation of the machine to insure proper movement of the web, proper sizing of the bill sections, and accurate orientation of the impressions on the billsection.

A further object of the invention is to perforate the web at transversely and longitudinally spaced intervals whereby properly located perforations will be provided on each of the bill sections.

A still further object of the invention is to provide a bill section safety and control device in connection with one of the printing couples including a permanent form from which impressions are made on the bill sections.

Other and further objects of the invention are to provide a machine which will be simple and (Cl. 101-47) a economical in construction and eflicient and posi tive in operation.

In the accompanying drawings I have illustrated a printing machine of the kind disclosed 40 in my co-pending application, Serial No. 459,599, filed June 6, 1930. This machine includes a main frame l5 (Figs. 5 and 8) supported on legs l6 rested on a suitable support. Also rested on this support are standards, such as IT, (Fig. 8) on which a supply roll of paper is rotatably supported, and a web W is led from the supply roll and is passed over a roller [8 carried by a frame l9 and in this manner a diabolo is provided to keep the web taut. The web W may be directed to a device for positively feeding the web to the printing machine, as will be described hereinafter, and it may be directed to a perforating device whereby holes may be punched therein at spaced intervals longitudinally and transversely charged into a suitable receptacle.

thereof, and a mechanism for accomplishing this will likewise be described hereinafter. The web is led to a guide roller 20 (Figs. 5 and 8) rotata bly mounted in the frame 2| from whence it may be directed through a suitable printing couple as described in my referred to co-pending application so that impressions may be made on one face thereof. In the embodiment of the invention illustrated in Fig. 1 the machine does not include such a printing couple and herein the web is directed to a guide roller 20'. After passing through the printing couple adjacent the roller 20 or after passing over the guide roller 20' the web is directed to a suitable feeding de- I vice,-to be described, and then to a cutting mechanism 22 which severs sheets S from the webW, and these sheets are deposited on conveyor belts 23 (Figs. 1, 5 and 8) to be carried over the table 24 into position below the platen P. During this movement each sheet successively engages the stop fingers 26 which are sequentially moved into stopping position to thereby orient the sections of the sheet below the platen P, said platen making impressions on the sheet from printng devices D (Fig. 4). These printing devices are introduced into the magazine M, (Fig. l) disposed rearwardly of the platen P, and are withdrawn from the magazine and moved in a step-by-step manner into printing position'below the platen. after which the printing devices are discharged from-printing position, in the manner well understood, to be collected in a galley G. After the sheet S has been stopped by the last of the stop fingers 26 and an impression has been made thereon, it is moved along by the belts 23 to a printing couple C mounted in the frame 21 andfrom this printing couple the sheets are dis- The printing couple 0 may be, for example, one of the type disclosed in the application of Curtis George Kranz, Serial No. 404,092, filed November 1, 1929, now Patent No. 1,955,814, patented April 24, 1934, but it is to be understood that any suitable printing couple may be used at this position. It is therefore apparent that a roll of paper may be mounted at one end of the machine and that a web may be led therefrom which may be directed to a 'printing couple wherein impressions will-be made at spaced intervals on one face of the web. From this printing couple the web is directed to a severing device, which divides the web into sheets, said severing device dividing the web intermediate the impressions made thereon by the printing couple so that these impressions will be neatly oriented on one face of 'each of the sheets. The severed sheets are then moved along into printing position below a platen which makes .impressions from variable printing devices on the face of the sheet opposite that on which the impression was made from the previously described printing couple. Prior to the time the sheet is severed from the web it is scored which divides the sheet into a plurality of sections such as a main body and one or more stubs and the 0 platen P operates to make an impression on each of these sections, the stop fingers 26 positioning the sheet to permit the impressions to be so located. After the platen has made an impression on each section of the sheet, the sheet then passes to a printing couple wherein an impression is made on the same face of the sheet as that on which impressions were made by the platen, and the sheets are then discharged into a suitable re- I ceptacle wherein they are collected.

which bill sections, such as utility bills, insurance notices and the like, may be printed to receive impressions on both faces or only on one face thereof and on the main body and the stubs thereof. V

A step-by-step movement is imparted to the web to feed it through the severing device so that sheets of a predetermined width may be severed therefrom and such a step-by-step movement is imparted to the web both when it is directed about the roller 20 and through the printing couple and when it is directed about the roller 20' when no printing couple is provided. This means for feeding the web in a step-by-step manner is illustrated in detail in Fig. 8a and as shown therein the web is directed over a ledge roller l8 so as to pass therebelow. A pair of rollers I9 and 2| are mounted in the frame 2| in vertical alignment and after being passed below the roller IS the web is directed between the rollers l9 and 2| to the cutting mechanism 22. The roller I9 is mounted on a. shaft 23' at the outer end of which there is a pinion I13 (Fig. 8) which meshes with a segment "2 on a rocker I'll. A crank 24 is connected to the rocker Ill and is mounted on a shaft 25' which extends across the frame 2| to receive a rotary movement in the manner which will be described hereinafter and as this shaft is rotated, the crank 24' is reciprocated and likewise the rocker I'M. A clutch 30 is interposed in the shaft 23 and operates so that the roller I9 is rotated only during the upward movement of the segment 25 and in this way a step-by-step movement is imparted to the roller I9. At the end of the shaft 23 opposite that carrying the pinion 13 is a gear 26' and meshing therewith is a gear 21' fast on the shaft 28 carrying the roller 2|. The step-by-step movement imparted to the shaft 23' is transmitted through the gears 26' and 21' to the shaft 28' to the roller 2| and therefore both the rollers l9 and 2| receive a step-by-step movement and the magnitude of this movement is suflicient to feed the web the width of sheet to be severed therefrom and subsequently deposited on the tapes'23. The crank 24' is adjustable so that the width of the sheet may be varied and this adjustable crank is described-in detail in my (:0- pending application, Serial No. 459,599, filed June 6, 1930.

In a machine of the above described type, impressions will be made by the platen from every printing device passing therethrough, but this is not always desirable for it may not be necessary to make an impression from every printing device introduced into the magazine M. I have therefore provided a device whereby only determined of the printing devices will be used in a printing operation and the other printing devices will be passed through the machine without an impression being made therefrom. In an ordinary printing machine when certain of the printing devices are not to beprinted or, as it is termed, skipped, the platen is rendered inoperative. However, in the present machine wherein additional mechanisms are provided, such as two additional printing couples, a web feeding mech- .5 The determination as to whether or not a printing device is to be used in a printing operation is brought about by a suitable selector device which includes a detecting member that acts on the printing devices withdrawn from the magazine M, this usually being done on the printing device immediately behind the one in printing position, this location being known as selector position. The detecting member located at selector position acts on identifying means on the printing device in this position and this identifying means may be in the form of tabs, openings or the like, located at predetermined positions on the printing devices so that when the detecting member of the selector acts thereon, the printing device will be printed or skipped depending upon the set-up of the selector.

It is within the purview of my invention to provide a detecting member of approved form which will operate a suitable selector device. I have, however, in the present instance, shown a detecting member and-a selector device of the type dethenose of a pawl 30 pivotally mounted at 3| on a disc 32 fast on the shaft 28, a spring 33 normallyacting on the tail of the pawl to hold the nose thereof engaged with the lug. When the tail of the pawl is engaged, in the manner to be described, the nose is disconnected from the lug and consequently the sleeve 28' is disconnected from the shaft and the platen P is not operated. At this same time the other mechanisms in the machine, save the printing device feed mechanism are rendered inoperative, and this is brought" about by the cooperation of the detecting member 34 with the identifying means on the printing devices D. In the present instance this identifying means is in the form of tabs T and the detecting member has one or more pins 35 removably mounted in selected openings therein to cooperate with tabs located at predetermined positions on the printing device to thereby determine the selection. Each time the printing device feeding mechanisms are operated to move a new printing device into printing position the detecting member 34 is moved toward the tabs on the printing device D in selector position.

The printing device feed mechanism employed herein is of the character described in the referred to application of Walter T. Gollwitzer, and this mechanism includes a rocker 36. The detecting member 34 is pivotally mounted on a rocker 38' mounted on the frame l5 at 31 and an arm on the rocker 36 engages the rocker 38' on each operation of the rocker 36 tomove the pins 35 in the detecting member toward the tabs on the printing device D in selector position, the manner in which this is brought about being clearly described in the referred to Gollwitzer application.

If one or more of the pins 35 engage a tab or tabs T the movement of said detecting member is arrested but if the pins do not engage a tab, the detecting member moves into a position beyond that in which it would have been stopped had the tabs been engaged thereby. consequentlfitljiis detecting member is stopped in j what may i be either an upper or lower position, the upper osition being the one in which it is stoppedwhen'the pins engage a tab. As is described in the referred I to Gollwitzer application, the stopping ofth'e' detector member in the upper position so locates the index segment 35 thatthe lug 36' willbe held out of the notch' iil' and this causes the latchpawl 38, plvotally mounted on the frame l5, to be locked in such a position'thatthe notched nose 39 on the "plate 46, secured to the amt, will latched'in the hotel-r46 in 'thepawl' jfl. Should, however', the detector member move into the lower position, this latching does not occur. I

When the latching operation is i brought about the throwout arm 4,2 connected to the arm Alfis disposed in such a position: that the -tail of the pawl 30 jengages'therewith to disengage the nose of the pawl from the lug 29 to thereby interrupt operation of the platen." This also so positionsthe arm 43 that a clutch 44 in the driv'ingmechanis'm is disengaged. i The shaft 28'is constantly rotated when' the machine is in operation and this shaft is rotated from the shaft 45, f(Fig. 1) these shafts being interconnected through the bevel gears 46' and 41'.

Rotatabl'y mounted on the shaft'45 i s'a flywheel 46 to which power is supplied from a suitable source such as an electric motor, the flywheel being connected to the shaft by the clutch 41. Since the shaft 28 is constantly-operated, 1 provide a means for driving the printing device'feil mechanisms therefrom and this includes an eccentric 48 having a band 49 thereabout carrying a connecting rod '56 extended through a sleevefli l pivotally connected to the rocker 36. Mounted on the sleeve 5| is a pawl 52 engageable with a collar 53 fast on the connecting-rod 50 and whenthe pawl engages said collar the sleeve 5| is attached. to the connecting rod to move therewith. It has been stated that the sheet embodies a number of sections and that impressions are made from the printing devices on each of these sections and therefore each printing device -remains inpr'in't ing position until the platen has made the required number of impressions therefrom. In the present instance a three-section sheet is being printed and consequently each printing device remains in printing position until three impressions have been made therefrom. This is accomplished by disconnecting the pawl 52 from'the collar 53 during two operations of the platen operating shaft 28. To accomplish this, a gear 54 fast on the shaft 28 meshes with a gear 55 fast on the shaft 56 suitably supported in the machine. The ratio between the gears 54 and 55 will be equal to the number of sections on the bill and hence in the present instance the ratio will be three to one so that the gear 54 will make three revolutions to one of the gear 55. J ournaled in a bracket 51 is a shaft 58 and a universal connection 59 extends between the shafts 56 and 58. The shaft 58 makes but one revolution to three of the platen operating shaft. On the shaft 58 is a cam 60 engageable with a roller 6| on the arm 62 medially mounted at 63 on an arm 64 which is pivotally mounted at 65 on a lug 66 on the frame i5. A

engages the pin 10 and holds the pawl 52 out of locking connection with collar 58 but when the cam 68 engages the roller 8| the arms are so moved that the pawl is permitted to lock the sleeve to the connecting rod 58 whereupon the rocker 36 and the printing device feed are operated. Thus, when the ratio between the gears 54 and 55' is three to one the printing device feed will only be operated once to every three operations of the platen shaft, and consequently if the sleeve 28' is connected to the platen shaft the platen P,

will be operated to make three impressions on the sheets and the sheets will be oriented relative to the platen by the stop fingers 26. In Fig. 1 I have shown four stop fingers 26 but when a three section sheet is being printed only three of these stop fingers will be operated, the fourth stop finger being provided for use when a four-section sheet is to beprinted and it is to be understood that a greater or less number might be provided.

It has been stated that the arm 48 is moved and held in a certain position when the notched nose 39 latches in the notch 48'. On this arm 43 there is a depending portion II (Fig. 2) carrying a roller 12 engageable with the roller I8 on the arm I4 pivotally mounted at I5. The arm I4 includes a throwout arm I6 and when the arm 48 is held in the position above described the throwout arm I6 is so disposed that it will engage the tail II of the pawl I8 of the clutch 44 to disengage the nose I8 of the pawl from the notch 88 in the collar 8I fast on the drive shaft 45. The

pawl. I8 is pivotally mounted on the gear 82 and.

when the nose 19 is disengaged from the notch 88, the movement of the gear 82 is interrupted. The gear 82 meshes with a gear 83 fast on the shaft 84 which has a bevel gear 85 thereon (Fig. 1) that meshes with a bevel gear 86 on the cam shaft 81' which operates the cams that control the stop fingers 28. Also fast on the shaft 84 is a bevel gear 81 (Figs. 1 and 2) which meshes with a bevel gear 88, and this bevel gear 88 drives through a suitable gear train to operate the severing device 22. This gear train also operates the shaft 25' to drive the web feeding mechanism.

When a printing couple BP, such as that disclosed in Figs. 5 and 8, is used it is also driven from these intermeshing gears 81 and 88. Consequently, when the roller I2 acts on the roller I3 to position the throwout arm 16 in the path of the tail II of the pawl I8 to disconnect the nose I9 from the notch 88 operation of the cam shaft 81' is interrupted and operation of the printing couple BP is likewise interrupted. Operation of the severing device is also interrupted as well as the web feeding mechanism and operation of the conveyor belts 23 is also stopped, these belts being driven'in the manner set forth in my previously referred to co-pending application. It is therefore apparent that when the clutch 44 is disengaged operation of the various mechanisms in the machine, save the shaft 28 and parts driven therefrom, is interrupted. The platen which is driven from the shaft 28 is not operated inasmuch as the sleeve 28 will be disconnected from the shaft 28 but the gears 54 and 55 will continue to operate. These gears drive the printing couple C which includes a permanent form that makes impressions on the same face of the sheets as that receiving impressions from the printing devices D. This printing couple however will not operate by reason of a safety device which prevents operation of the printing couple when no sheet is in position to be printed thereby.

This safety device cooperates with a printing couple C which includes an impression cylinder 89 (Fig. 14) having an electro-plate or other suitable printing form fast thereon and cooperating with this impression cylinder is a platen cylinder 98 having a blanket thereon. The cylinder 88 is mounted on a horizontal shaft which is driven from the vertical shaft 9| that has a bevel gear 92 thereon which meshes with a bevel gear 98 fast on the shaft 58 whereby the shaft 9| and consequently the cylinder 89 will be driven with the shaft 28. On the shaft carrying the cylinder 89 there is a spur gear (not shown) 'which meshes with a spur gear 94 fast onthe shaft 95 iournaled' in the frame 98 pivotally mounted at 91, and this frame is raised and lowered to and from printing position, this being controlled from the cam 98 fast on the shaft 56 and riding on the cam 88 is a roller 88 which follows the cam to regulate the raising and lowering of the frame 96 and therefore the platen cylinder. On the frame 21 there is a shoulder I8I engageable with a shoulder I82 on the arm I88 connected to the shaft I84 having a roller I85 thereon. The shaft I84 is carried by the clamp frame I86 which is pivotally supported in a suitable manner and which embodies an arm IN on which there is a roller I88 that engages the face cam I89 on the cam 98. A rise on the face cam acts on the roller I88 to pivot the clamp frame I86 and the shaft I84 to elevate the roller I85 at a predetermined time in the cycle of operation. In vertical alignment with the roller I85 is a peripherally grooved roller H8 and when no sheet S is in position below this roller and the roller I85 is permitted to move downwardly it will move into the peripheral grooves in the roller I I8 to position the shoulder I82 below the shoulder I8I to prevent the frame I86 from being pivoted downwardly, for the gear84 always meshes with the gear on the shaft carrying the impression cylinder 89, but since the impression cylinder cannot be lowered when the shoulders I82 and I8I are engaged no offsets will be formed on the blanket on the platen cylinder 88. When. however, a sheet is disposed below the roller I85, said roller is prevented from passing into the peripheral groove in the roller H8 and therefore the shoulder I 82 is held from engagement with the shoulder I8I. This permits the frame 96 to pivot downwardly and the platen cylinder will act to make an impression from the printing cylinder onto the sheet S which will have been released to pass between these cylinders and below the roller I85. The sheet S is stopped by the finger III carried on the arm I I2 on the shaft II3 which includes an arm II4 having a roller I I5 thereon riding on the face cam II6 fast on the shaft 56. The face cam II6 operates in timed relation with the cam 98 and acts to elevate the fingers I I I immediately following the time the shoulders I82 and I8I would be engaged so that a sheet may move between the cylinders 89 and 98. In order to insure movement of the sheet, a clamp roller I I1 is provided which is carried by the frame II 8 on which there is an arm carrying a roller I I9 meshing with the periphery of the cam II 6 and at the time the finger II I is raised, the roller II I is lowered to thereby clamp the sheet onto the pulley III to insure movement thereof between the cylinders 89 and 98. It is manifest that the foregoing arrangement includes but two cams which control the operation of the printing couple and when the selector functions to interrupt movement of the sheets and no sheet moves into position below the roller I85 it is apparent that the printing couple C does not function to make an impression. The particular operation of the printing couple C is described and claimed in-the co-pending application of Curtis George Kranz. Serial No.

403.092, filed November 1, 1929, to which reference may be made for the details of construction. It has been pointed out thatunder certain conditions of operation it is desirable that the web be perforated and" these perforations are to be spaced both longitudinally and transversely in the web W. To accomplish this, a bracket I20 (Fig. is fast to the frame 2| and carriesa strip I2I (Fig. 7) havinga T-shaped slot I22 therein in which the head of clamp boltsfI23 may be secured. The clamp bolts I23 serveto. lock the bearings I23 in transversely adjusted positions on the strip I2I. Another strip I25 is carried by thebracket I23 and has a slot I26 therein in which the heads of clamp bolts I21 may be arranged, these clamp bolts serving to retain bearings I23 in transversely adjusted positions on the strip I25. .The bearings I23 and I23 are aligned in cooperating pairs and the female portion I29 of a perforating die is arranged in each of the bearings I23. The perforating plungers I30 of the dies are slidably mounted in the bearings I23 and are acted on by springs I3I to be urged away from the female portions I29. Journaled in the bracket I20 is a shaft I32 carrying fingers I33 which are aligned with the plungers I30. On the shaft I32 is an arm I33 to which the lower end of 'a link I35 is pivotally connected, said link having a yoke I35 at the opposite end thereof dis- I35 to pivot the shaft I32 to thereby quickly move the fingers I33 to thus force the plungers I30 through the web W and into the female portions I29 of the dies to thereby perforate the web which is directed about rollers I30 and MI in the bracket I20 and from the roller I the web is extended between the bearings I23 and I23 to a roller I32. From-the roller I32 the web is directed about-rollers I33 and I33. The rollers I33 and I33 are carried on a plate I35 which has end plates such as I36. On one of the end plates I36 is a stud I31 extending through an arcuate slot I38 in the plate I33 carried by the frame 2I. By loosening the clamp stud I31 the end plate I35 may be moved into adjusted positions to thereby vary the space between the rollers I33 and I32 and by so doing the extent of the web between the rollers MI and the printing couple may be varied and by so doing the position of the perforations relative to the impression may be varied.

A positive web feed for withdrawing it from the supply roll may be provided to reduce excessive tension in the web feeding means. The web W is directed from the supply roll about a roller I6 carried by the frame I9 to provide a diabolo. From the roller I3 the web is directed to a roller I53 (Fig. 8) and thence to a roller I5I.- From the roller I5I the web is directed about a spool I52 and from this spool the web is directed to the roller 20 to be passed through the machine as previously described. The spool I52 is thus arranged in a bight in the web W, said bight being defined between the rollers I5I and 20. A pair of arms, such as I53, are provided which support a trough I53 into and from which the spool I52 may move. The arms I53 are pivotally mounted at I55 on the'standards I1, and when the spool I52 movesinto the trough I53 the arms I53 are pivoted downwardly. Connected to one of the -arms I53isarod I53normallyurgedinanupward direction by" the spring I51 extending between a clamp on the rod I53 and a spring anchor fast on'the bracket on the frame 21. The upper end of the rod I53 is connected to a plate 53 rotatably supported about the shaft I59. on one face of the plate I53 are cam sur- -faces I52 and cooperating therewith are rollers I53 carried by the frame 2I adjacent the bearing I53 in which the shaft I59 is journaled. When the rod I55 is moved downwardly by reason of the seating of the spool I52 in the trough I53, the plate I59 is rotated about the shaft I53, a sleeve I65 being disposed between said plate and the shaft I59. As the plate is thus turned the cam surfaces I52 move over the rollers I53 and the plate I53 is thereby slid axially along the sleeve I55. Juxtaposed to the plate I53 is a ring I35 and a spring I51 is disposed about the sleeve I55 between the ring I35 and the plate I53 and normally urges the plate away from said ring. Carried on the shaft I59 is a roller I55 and the web is directed between this roller I53 and the roller I50. Thus, each time the shaft I59 is rotated the web will be advanced. In order to operate the roller I59 I provide an arm I59 which is pivotally mounted at I10. As described in my co-pending application, Serial No. 459,599, filed June 6, 1930, previously referred to, an arm "I, unitary with the arm I59, carries a segment I12 meshing with a pinion I13 which is alternately r0- tated in opposite directions to thereby impart a reciprocatory movement to the arm I1 I and consequently the arm I59. On the arm I59 is a segment I12 meshing with a pinion I 13 rotatably mounted on the shaft I59. Fast to the pinion I13 is a collar I13 including a depending arm I15 carrying a pawl I15 engageable with the ratchet wheel I11 fast to the shaft I59. Thus, upon movement of the segment I12 in one direction the K pawl will seat in the teeth of the ratchet and consequently movement will be imparted to the shaft I59, but upon movement of the segment in the opposite direction the pawl will merely ride over the teethof the ratchet and no movement will be imparted. At the time the spool I52 seats in the trough I53 the bight formed in the webw will be of proper size and no more paper is to be fed until the extent of this bight is reduced. Thus, when the spool seats in the trough to move the rod I56 downwardly, which causes the plate I58 to be moved along the sleeve I55 as has been described, the bevelled shoulder I13 will engage the boss I19 on the pawl I15 and will pivot this pawl downwardly out of engagement with the teeth on the ratchet I11 and therefore even though the arm I59 is reciprocated no movement will be imparted to the shaft I59 and consequently the roller I58. But as soon as the extent of the bight is reduced, thespool will move from the trough I53 and the spring I51 will move the rod I55 upwardly and the plate I58 will be permitted to move away from the ring I55 and the bevelled shoulder I13 will be disengaged from the boss I19 whereby the pawl may again seat in the ratchet and operation will be carried out as previously described.

In the foregoing I have described a printing machine to which a web may be directed from a supply roll and I have described how this web may be fed in a positive manner. I have also described how the web may be perforated and how these perforations may be located at transversely and longitudinally adjusted positions in the web. Furthermore, I have described how sheets may be severed from the web and passed through the machine below the platen to receive impressions from changeable printing devices,

moved into position below the platen.- I have also set forth how a printing couple may be provided which will make impressions on one face of the web and preferably this printing couple makes impressions on the face of the web opposite that receiving impressions from the changeable printing devices. I have also shown that a selector may be provided in the machine which will function to render the just described mechanisms inoperative when a printing device that is to be skipped is moved into printing position, and I have shown how all of the foregoing mechanisms may be rendered inoperative save the printing device feed mechanism. Moreover, I have described how the sheets may be passed to another printing couple after having received impressions from the changeable printing devices and this printing couple is employed to make impressions on the same face of the sheets as that on which impressions are made from the changeable printing devices. Furthermore, I have shown how this printing couple may be rendered inoperative when no sheet is in position to be printed thereby and manifestly this device will cooperate with the selector to prevent operation when the selector functions to stop the sequential passage of sheets through the machine.
